Vidya Balan recently did a small act at the Screen Awards with Shah Rukh Khan where she addressed the superstar as 'brother'. However, she says calling SRK brother saddened her.

"I did not find that act interesting. I felt very sad that I called him my brother. The world can call Shah Rukh their brother, but I will never call him my brother," the 33-year-old said at the DVD launch here of her movie "The Dirty Picture".

After taking away all the awards for her performance in "The Dirty Picture", Vidya is currently busy promoting her next film "Kahaani".
